The screen size of a television is determined by the length of the diagonal of the rectangular screen. traditional elevisions come in a 4: 3 format, meaning the ratio of the length to width of the screen is 4 to 3

what is the area of a 17in traditional tv screen? what is the area of a 17in lcd tv whose screen is in 16: 9 format? which screen is bigger?

the area of a 17 inch traditional tv is approximately sq inches

lcd " "
(do not round until the final answer. then round one decimal place as needed)

Part 1) The area of a 17 in traditional tv screen is

Part 2) The area of a 17 in LCD TV screen is

Part 3) The screen of the 17 in traditional TV is bigger, because its area is greater than the area of the LCD TV

Step-by-step explanation:

Let

x ----> the length of the rectangular screen

y ----> the width of the rectangular screen

Part 1) What is the area of a 17 in traditional tv screen?

we have

----> equation A

Applying the Pythagorean Theorem

----> equation B

substitute equation A in equation B

solve for y

take square root both sides

Find the value of x

Find the area of the rectangular screen

The area is equal to

substitute

Part 2)  What is the area of a 17 in LCD TV whose screen is in 16:9 format?

we have

----> equation A

Applying the Pythagorean Theorem

----> equation B

substitute equation A in equation B

solve for y

take square root both sides

Find the value of x

Find the area of the rectangular screen

The area is equal to

Part 3) which screen is bigger?

Compare the areas

therefore

The screen of the 17 in traditional TV is bigger, because its area is greater than the area of the LCD TV

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:
